These are the Mexicanised variations of Bisexual, Rainbow, Leather and Bear
Flags. All designed by Francisco J. Lagunes & Miguel Angel Corona in 2001.
Were used in public in the Mexico City Pride Parade 2002.Francisco Javier Lagunes Gaitán, 10 September 2003.

A design of Mexican gay rainbow flag is presented here.
Another gay rainbow flag, derived from the national flag by replacing
green and red fields by six rainbow colors, has first appeared at the
GayJourney.COM
where it is marked as having been designed by the site’s author, Greg
Gomes. The images of this flag have been appearing at the Web for
years as illustrations of LGBT-related articles, but the real flag was
eventually manufactured and offered for sale at
eBay. There, white field seems to be a bit wider than the rainbow patterns,
while it was visibly narrower in the original image. Also, the flag
looks less oblong than the declared ratio of 3:5, which was used in
the attached image, in which the white field was also made as wide as
the rainbow patterns, to model it more after the national flag, but
also to avoid the contradictions about its width.

Mexican gay flag proposed by Greg Gomes and presented at
GayJourney.COM.
Two photos of this flag, taken in the Castro neighborhood of San
Francisco, California on 2015-07-30, can be found here:
Wikipedia [01] and
Wikipedia [02].
The flag shown in the first photo has the white field approximately as
wide as the rainbow patterns and the ratio of about 2:3, while the one
in the second photo has the white field visibly wider than the other
two and the ratio might be the same or a bit more oblong.
